' Report-Soil and Groundwater Investigation Herman&Helen's Marina September 30, 1996 ' Page 7 3.5.1 Analytical Results - Soil ' Five (5) soil samples (1 sample per borehole) were retained for chemical analysis. Each sample was labeled according to the project number, the borehole number, and the depth at which the ' sample was collected. ' The laboratory analyses indicate concentrations of TPH-G, BTEX, and MTBE in the soil sample collected from GP-4 at 5 feet bgs. A lower concentration of MTBE was detected in the ' sample collected from GP-3 at 10 feet bgs. TEPH (motor oil) was detected in GP-2, GP-3, and GP- 4, at concentrations ranging from 39 to 55 mg/kg, however, the laboratory indicated that the organics ' detected during the analysis were within the motor oil range but did not match the motor oil pattern. The organics detected in the TEPH analysis may be associated with the high organic (peat) content in the soil. The results of the soil analyses are shown in Table 1, below. Laboratory report sheets indicating analytical methods used, detection limits, and results of analyses are located in Appendix C.
